FAQ’s About London Sash Window Installations

Can Sash Windows be Double Glazed?

Modern sash windows can be double glazed, but if you are in a listed building or conservation area where you are not allowed to replace your sash windows with double glazing, you can look at applying secondary glazing to your London property.

Are Sash Windows Energy Efficient?

Sash windows are energy efficient. The sliding sash windows feature a six chambered profile. The unique design will trap warm pockets of air and retaining heat for longer. This enables the windows to achieve an impressive BFRC Window Energy Rating.

Should I Repair or Replace Sash Windows?

You can repair sash windows but you should replace them. You may notice that over time, you’ll spend more money on repairing the window, making it a less cost effective option. Replacing an entire window will be the most cost effective solution, as our sash windows have been carefully crafted to stand the test of time and are competitively priced. The modern design will not rot, warp, fade or crack, meaning you can enjoy your new windows for years, without the need to repair or replace them.

Do You Repair Sash Windows?

We do not carry out sash window repairs as we only install uPVC sash windows. We recommend a full replacement instead of repairing an existing window, as this will be more cost effective in the long term.

How Long Do You Take to Install Sash Windows?

The time we take to install sash windows will depend on the size and style. However, this can take us up to anything from a few hours to a full day. We aim to carry out the installations with minimal disruptions to your home life, ensuring everything is left extremely clean and tidy.
